a Germany Application December In Germany 5, 1936, Serial No. 1l4,488 December 19, 1935 s Claims. (01. iii-8t) F This invention relates to w an inflatable toy balloon having an outlet nozzle for the introduced air for the purpose of imparting a lift to the balloon. In this connection it is necessary that the aperture of the nozzle be made comparatively large, as otherwise the lift will be too small. A comparatively large nozzle aperturehas, however, the disadvantage that the air within the balloon escapes too quickly so that the balloon again falls to the ground in a. very short time. V

It has been found that the lift is; considerably assisted ii the nozzle is made in cup-like form, i. e.,,is furnished'with a bottom which contains the outlet aperture, and the edge ofthe said outlet aperture is passed inwardly upwards. If it is desired to produce a hissing or whistling noise (1 ng the time when the balloon is inlthe air, there is provided in spacial disposal to the first bottom a second bottom which is also furnished with'an outlet aperture. I I

To assist the lifting effect and at the same time to cause the balloon to remain for a longer time in theair there maybe providedaccording to the invention, in place of a simple nozzle, aninjectorlike compound nozzle, the outer portion of which possessesin its wall openings for sucking in air from the outside. To increase the injector effect the inner portion of the nozzle is furnished with erably the arrangement will be such that the distance between the two orifices is capable-oi adjustment. This adjustment may be obtained by a threaded connection: between theiinner and outer portions of the nomle. This adjustment'of the spacing between the two apertures may be utilized to compensate any difference in the tension of the balloon material. The air passing at a high speed through the constricted inner nozzle picks up within theouter nozzle air from the outside passing in'through the op rigs in the outcr nozzle, which outer air is e lled through'theouter nozzle and assists to 1m art the lift.

' Since the outletaperture oi the inner nozzle, owing to itaconstricted form, -is not adapted for rapid inflation of the balloon, it is desirable to furnish the inflation tube of the balloon" with a sleeve, over which the nozzle may be fitted after the inflation. The inflation tube 'may closed. in the known fashion by means'of a resilient clip.

Various embodiments of the invention are illustrated by way'of example in the accompanying drawing.

Fig. l is a view of a balloon showing in section a nozzle constructed in inj ctor-like form.

Ilg. 2 -shows the inflation tube with the sleeve, an Fig.. 3-is an elevational view of the two-part nozzle removed from the sleeve.

Fig. 4 shows a resilient clip for closing the in:- 5 fiation tube of the balloon.

In the embodiment according to Figs. 1 to 3 the nozzle is constructed as a compound nozzle acting in the manner of an injector, there being fitted or screwed over the cylindrical part of the nozzle a a second nozzle d the orifice of which is in certain spacial disposal to the orifice c3 of the inner nozzle 0 and the wall of which is furnished with openings (1 for sucking in auxiliary or secondary air. The aperture of the outer. nozzle d is preferably larger in cross-section than the aperthreaded connection between the cylindrical portions. The two-part nozzle is fitted by means or the cylindrical portion of the inner nozzle, 0 on to a sleeve b over'the end beading l; of which there is slipped the inflation tube of the balloon a The nozzle fitting over the sleeve 11 also'pro tects the latter against. contamination when the balloon after escape of the air again falls to the ground. f

For the purpose of inflating the balloon a the two-part nozzle 0 d is capable of being removed been introduced the inflation tube a? is closed by application of the resilient clip e as indicated in dash-dotted lines in Fig. 6. After the nozzle c d has again been fitted on the sleeve b the balloon is ready for use.-and will commence to rise .upon removal of the clip e The air passes out at high speed through the orifice c sucking up auxiliary airthrough the openings d and escapes together with this auxiliary'air through 40 the orifice in the outer nozzle al This latter orifice is of such size that a sufiicien't degree of lift is obtained, whilst the escape of the airfrom the balloon is determined by the narrow'apertur'e c so that in consequence the balloon will remain 4 7 inthe air for a,comparatively long time before its supply of air has been fullyconsumed.

It will be understood that no limitation is made to the specific forms of embodiment shown, and

that numerous modifications are quite possible 50.
